Evaluation of Soil Removal from Cotton Fabrics

Abstract

Certain characteristies of a soil-fiber complex are critically important to valid com parison of the relative soil removal abilities of washing machines and detergents. These characteristics, stated herein, are obtained by a method of direct precipitation of zirconyl phosphate soil in cotton fabric. Soiled test cloths thus prepared permit evaluation of soil removal with a high degree of preciston and reproducibility.
